Eagle Chevy 454 4.000in Crank 6.135in I-Beam Rods -3cc Flat Top 4.320in Pistons Balanced Assembly

If you're building or rebuilding a Chevy 454 engine for street use, this balanced rotating assembly from Eagle is a solid choice. It's designed for naturally aspirated, pump gas applications, meaning it's built to handle the demands of everyday driving and occasional spirited runs without needing special fuel. This assembly includes all the core components you need to get your engine's bottom end put together, balanced and ready for installation.

At the heart of this assembly is a 4.000-inch cast crankshaft, paired with 6.135-inch I-beam connecting rods. These rods are secured with 7/16-inch ARP 8740 bolts, known for their strength and reliability in performance applications. The pistons are forged 4032 aluminum from Mahle, featuring a -3cc flat top design and a 4.320-inch bore size, which are crucial for achieving the correct compression ratio with your cylinder heads. This assembly also comes with plasma-moly file-fit piston rings, giving you the flexibility to achieve a perfect seal in your cylinder bores, and King SI rod and main bearings to ensure smooth rotation and proper oil clearance.

This rotating assembly comes pre-balanced, which is a significant time and labor saver during engine assembly. Balancing is critical for engine longevity and smooth operation, especially at higher RPMs. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
